Add...
    -format %s -identify

just before the final save, and IM will output to stdout the scene
(image) number of each image.  Grab the last number and add one
or count the number of lines it outputs.


For example, here is a rose animation that morphs a rose to its
'flipped' form, then back again, with a pause at the ends of the morph.

  convert rose: \( +clone -flip \) -set delay 200 \
          \( -clone 0,1 -morph 10 -delete 0,-1 -set delay 10 \) \
          \( -clone 1 \) -delete 1    \( -clone -2-1 \) \
          -format %1 -identify   rose_flip.gif

  0
  1
  1
  ...
  20
  21

result 22 images (original, flippes, plus two X 10 morphing images.

Synopsis.
  read in rose image, create its flips form, set the pause time delay
  create just the morphing sequence images,  set morph speed
  move original 'flipped' image end,  duplicate morph images (reversed)
  output a count total number of images, and write the resulting animation.

Enjoy



The above example will appear in IM examples at
